Mix together butter and sugar. Spread it on both sides of the bread. Heat a non-stick frying pan over middle high heat. Fry each slice of bread on both sides until golden. Don't put it on the kitchen towel and don't stack slices while hot or they will stick. Serve hot.

Cut off the each end of bread, then slice baguette in half. Cut each half in three pieces. Brush each slice with softened butter and arrange them in a baking pan. Whisk the eggs, milk, sugar, orange juice and zest, vanilla and salt. Pour it over the bread and leave to soak for 30'. Flip the pieces around every 10'. After 30' pour off any left over liquid from the pan, sprinkle the bread with yellow sugar and bake in the preheated oven at 180C for 30'. Dust with powdered sugar and serve warm. If you serve it with some sweet topping (like jam, nutella...) omit the sugar in the filling.
